Description

Technical Field

[0001] This utility model relates to the field of centrifugal ductile iron pipe technology, specifically to an automatic centrifugal ductile iron pipe equidistant cutting machine. Background Technology

[0002] Centrifugal ductile iron pipe is a type of pipe produced using ductile iron as the material and a centrifugal casting process. This type of pipe combines the excellent mechanical properties of ductile iron with the high efficiency of centrifugal casting, and is widely used in drainage, water supply, sewage treatment, and other industrial fields. The centrifugal casting process involves pouring molten ductile iron into a rotating mold, where centrifugal force distributes the iron evenly. This process improves the density and strength of the casting and provides good control over the thickness and internal and external surface quality of the pipe. However, existing centrifugal ductile iron pipe equidistant automatic cutting machines still have certain shortcomings; for example:

[0003] The "Automatic Centrifugal Ductile Iron Pipe Equidistant Cutting Machine" with application number CN202322619998.0 includes a main body, an auxiliary body, and a slag removal body. The auxiliary body is located to the right of the main body, and the slag removal body is located below the main body. The main body includes a first movable support, a first cutting blade, a second movable support, and a second cutting blade. The first cutting blade is movably mounted on the left end of the first movable support, the second movable support is fixedly mounted below the first movable support, and the second cutting blade is movably mounted on the left end of the second movable support. This centrifugal ductile iron pipe equidistant automatic cutting machine, through the installation of the main mechanism, allows two sets of cutting blades, cutting blade one and cutting blade two, to work simultaneously. Compared with a single cutting blade, this significantly reduces the wear and tear of the cutting blades during operation, effectively improving the practicality of the centrifugal ductile iron pipe equidistant automatic cutting machine. As mentioned above, although this centrifugal ductile iron pipe equidistant automatic cutting machine can be used well, it cannot flexibly adjust the distance between the cutting blades when cutting raw materials, and it cannot intermittently convey raw materials, increasing the user's workload. The equipment has poor flexibility and automation, which often troubles users. Utility Model Content

A drive motor is fixedly installed on the left front end of the upper top surface of the bottom plate, and a bevel gear set is fixedly installed on the upper top surface of the drive motor.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This centrifugal ductile iron pipe equidistant automatic cutting machine allows the user to place the raw material on the conveyor belt, activate the electric push rod to drive the left slide plate, thereby driving the first and second connecting rods to adjust their angles, so that the four slide plates are equidistantly adjusted. Activating the drive motor drives the lead screw to rotate, causing the top plate to move downwards. Activating the transmission motor drives the rotating rod to rotate, which in turn drives the first intermittent wheel to rotate. The cooperation between the first and second intermittent wheels drives the conveyor belt to move intermittently, and the cutting blade moves downwards to cut the raw material at equal intervals. This allows the user to flexibly adjust the distance between the cutting blades according to different size requirements. Furthermore, the intermittent transport of the raw material on the conveyor belt reduces the user's workload and improves the working efficiency of the equipment. Attached Figure Description
